I use mfix to simulate CFD, but when i use Paraview to visualize, it is so blur. I have no idea to do with it. could anyone tell me why this happen and what should i do
Thank you very much

It looks like your issue is simply how your visualizing the data. In the drop bar for selecting things like T(Temperature) or U(velocity), there are two sets of the components. The first has an orange cube to the left of each one and the second set has a red circle.

It appears that you have the orange cube selected. This will give the data as per cell. As your mesh is coarse this gives your "blur" look. If you change it to the circle it will smooth your data giving it a more complete look.

Indeed, this is due to the coarse mesh.
Use the filter CellDatatoPointData and the visualization should be smoother.
Possibly generating a denser grid for the CFD simulation would help both the accuracy of the simulation and the visualization alike.
Hope that helps,
